To all whom. 27 may concern.'

Be it known that, Law itnN'rY., a citizen of the United States, :ind a resident ot Des Moines, in the county of Polk and State of used the reference numeral to indicate generally the eye glass run. or eye wire containing the lens 11.

The eye wire or rim 10 is ordinarily made 5 Iowa, have invented a certain new and uscin the form of a. broken ring.

ful Spectacle-Temple Structure, ot' which the following is a specification.

The object of my invention is to provide a spectacle temple structure of extremely simple and inexpensive construction having its parts, however, so arranged as to take from what has been the strongerpart of the structure and add to what has been heretofore the weaker' part ot the structure, so to produce a linished article, which will have the proper strength adjacent to Vthe hinge joint connection with the rim or eye wire.

v With this and other objects in view, my invention consists in the construction, arrangement and combination ol' the various parts of my invention, whereby the objects contemplated ere attained, as hereinafter more full set forth, pointed out in my claim, an illustrated in the accompanying drawings, in which:

Figure 1 shows a. perspective View of a spectacle temple structure embodying my invention.

Figure 2 shows a side elevation of the same. K

Figure 3 is a detailed, sectional View taken on the line/3 3 ot' Figure 2.

Figure ,4 is a detailed, sectional view taken on the line 4 4 of l1`i`gure 1.

There is agreat deal of complaint made to oculists and opticiens on account of the fact that the temples ot the spectacles break frequently at points close to the hinge joints thereof.

'lhe weakness of the temples at this point results in such requent breakage as to amount tol very substantial loss to spectacle Wearers and to afford considerable annoyance for opticians, oculists and optical companies.

It is my purpose to so rearrange the structure of thil temple and connecting parts as to do away with the weakness heretofore 1cxisliiug" and to all'ol'd a strong' sturdy strueture which will 'not break as the old structures do.

lu the accompanying drawings, l have Secured to the ends of the ring -or rim adjacent to the joint therein. are the end pieces l2 and '13. A short screw 14 is eX- tended through the upper end piece 12 and screwed into the lower end piece 13 for locking the end pieces and the adjacent ends ot the ringr l() together.

'lo avoid the weakness heretofore referred to, l have therefore provided my structure in which the adjacent faces of the end pieces are made cone-shaped as indicated at 18 and lt) in Figure 4.

The portion of the .temple l'adjacent to the joint, as at 20, is made much thicker than the flat portion 16 and that portion which is received between the cone-shaped portions 18 and ,19 of the end pieces is countersunk above and below, as shown at -21, in Figure 4 to -fit the cone-shaped portions 18 and 19.

The resulting structure'at the 'oint is of the same Vvertical thickness overall as in the old structure and ofl the same horizontal thickness, but the material ot'the temple itiselt' as at the portion 20 is of almostftwice the vertical thickness of the 'former structures. ,.1 i'

This gives a strong rigid temple having more than twice the strength in it adjacent to the joint, which is the weak spot, as is found in the old type of temple structures.

'lhe advantage ot such astructure is obvious. l

It effects great saving to the. user of spectacles and saves4 the ocnlist who desires to give his patients real service considerable embarrassment.

Practically all oculists recognize thede-v sirability of securing some structure which will eliminate the weaknesses of the ordinary temple structure. The attempt to moetI tlie-r'liiiicultv herein referred to is illustrati-.d in the Kirstein and Gage Patent, No. 1,478,661, issued December 25, 1923.

l claim as my invention:

1n a structure ot the class described, a split. lens rim and pieces mounted on the adjacent ends thereof, means 'for dctacheoV ably fastening said end pieces together, said end pieces having po1tons pro]ect1ng beyond sald means spaced from each other and formed with adj aeent cone-shaped faces,`

5 a temple having pronounced ythickness vertically and horizontally and having a portion received between said cone-shaped parts formed-,with countersunk recesses to recelve the cone-shaped parts, and means for locking the cone-shaped parts together With the-temple between them for permittino pivotal movement of they temple.
